I have a headache / stomachache. (我头疼 / 肚子疼。)

提出建议

He should drink more water. (他应该多喝水。)
She shouldn't eat too much candy. (她不应该吃太多糖果。)
It's a good idea to get some rest. (休息一下是个好主意。)
Why not lie down for a while? (为什么不躺一会儿呢？)
You'd better go to bed early. (你最好早点睡。)
使用情态动词表达“必须”和“不应该”
You must drink plenty of water. (你必须喝大量的水。)
He must stay in bed for a few days. (他必须卧床几天。)
You mustn't eat anything cold. (你不应该吃任何生冷的食物。)
She mustn't go to school today. (她今天一定不能去上学。)
核心语法
情态动词 must / mustn't 和 should / shouldn't 的用法
这是本单元最重要的语法点，用来表达义务、建议、禁止等。
| 情态动词 | 含义 | 用法 | 例句 |
|---|---|---|---|
| must | 必须，一定 | 表示强烈的义务或命令，主观看法。 | You must finish your homework. (你必须完成作业。) |
| mustn't | 禁止，不准 | 表示强烈的禁止，相当于 "must not"。 | You mustn't play on the road. (你禁止在马路上玩。) |
| should | 应该 | 表示建议、劝告或义务，语气比 must 弱。 | You should listen to your teacher. (你应该听老师的话。) |
| shouldn't | 不应该 | 表示否定的建议或劝告。 | You shouldn't stay up late. (你不应该熬夜。) |
重要区别：
must侧重于主观认为“必须”，而have to侧重于客观情况“不得不”，本单元主要掌握must。must和mustn't语气非常强烈,带有命令或警告的意味。should和shouldn't语气较为委婉,常用于提出建议。
have 的用法
have 在本单元有两个主要用法：
表示“有” (实义动词)
（图片来源网络，侵删）I have a new book. (我有一本新书。)
Do you have a pen? (你有笔吗？)
构成固定短语 (与名词连用,表示病症或动作)
have a + 疾病/症状：
have a cold(感冒),have a headache(头疼)have a + 活动：
have a rest(休息),have a try(试一试),have a look(看一看)have breakfast/lunch/supper (吃早/午/晚餐)
交际用语
看病场景

B: I have a fever and a sore throat. (我发烧，喉咙也疼。)
A: You should see a doctor. (你应该去看医生。)

Take care! (保重！)
Get well soon! (祝你早日康复！)
写作小贴士
在写关于“健康”话题的作文时,可以遵循以下结构：
开头： 描述自己的健康问题或关心他人的健康。
Example: I had a terrible cold last week.
中间：
Example: My mother told me to see a doctor. The doctor said I should drink more hot water and stay in bed.
Example: I had a high fever, a sore throat, and I coughed a lot.
描述症状： 详细说明你或他人有什么不舒服的地方。
寻求建议/给出建议： 讲述你做了什么（或别人建议你做什么）来恢复健康。
描述结果或总结经验教训。
Example: After three days' rest, I felt much better. From this, I learned that we should take care of our health.
